Side-clamp server lifter

A below-the-hook attachment for a floor crane. Two pads clamp the chassis side walls with a set, indicated force, and four webbing straps are fitted under it as an independent backup after a 65 mm lift-off. Nothing goes under the server to pick it up.

Rated load: 250 kg

Clamp mechanism

One handwheel drives a right/left-hand screw, so both arms close equally and stay centred. A sealed torque limiter clicks at 19.5 N·m, and disc-spring cartridges behind each pad turn the screw travel into a known clamp force.

Handwheel turns 0.0

Pad spacing: 600 mm
Clamp force / side: 0.0 kN
Indicators: below flush

Pads open. Lower the lifter over the server.
